See? I told you it would! Trust the Good Folk, they make your program run. :)

Hmmm. Yes, in fact it should. That code will end up with a list of 65
identical scalars in it. Bad Dan! No cookie for me.

That'll probably be:
get_temp P0
new P0, list
Dunno about preextending (which isn't bikeshedding, FWIW) since it doesn't
quite do what you want with arrays, and lists will be an awful lot like arrays.
